Side effects of clozapine in older adults with treatment-resistant schizophrenia compared to younger adults.

OBJECTIVES: To study the differences in side effects of clozapine between older adults aged ≥55 years and younger adults aged 18-55 years with treatment-resistant schizophrenia. METHODS: A retrospective cohort study in a large mental health institute in the Netherlands. All patients diagnosed with treatment-resistant schizophrenia who started with clozapine between 2011 and 2020 (N = 284) were included. We compared the number and type of side effects reported in the electronic patient files as well as the number of treatment discontinuations and the time until discontinuation, both due to side effects, of older adults versus younger adults. RESULTS: In the younger age group (N = 183), the number of reported side effects was significantly higher in the first 3 months of treatment (Mann-Whitney U = 7341.5, p = 0.004) and after those 3 months (Mann-Whitney U = 5668.5, p < 0.001) compared with the number reported in the older age group (N = 101). Sedation, hypersalivation, dizziness, tachycardia, heartburn, nausea, weight gain, and constipation were reported significantly more often in the younger age group, and only extrapyramidal symptoms were reported significantly more often in the older age group. There was no significant difference in the number of treatment discontinuations due to side effects (23% vs. 21.8%, Chi-2 = 0.051, df = 1, p = 0.821) and time until discontinuation due to side effects (b = 0.091, SE = 0.335, p = 0.798) between younger and older adults. CONCLUSIONS: Side effects of clozapine were reported significantly less often in older patients compared with younger patients. Older patients did not discontinue treatment due to side effects more often or earlier than younger patients. Older patients with schizophrenia may not be more vulnerable to side effects than younger adults.

The impact of personality traits on the course of frailty.

OBJECTIVES: Determinants of frailty are generally explored within context of somatic healthcare and/or lifestyle characteristics. To examine the impact of personality traits on change in frailty and the potential role of depression. METHODS: A 2-year follow-up study including 285 patients with a depressive disorder and 116 never-depressed controls. Multiple linear regression analyses were conducted to regress the Big Five personality traits (independent variables) on different frailty measures (dependent variables), including the Frailty Index, Frailty phenotype, gait speed, and handgrip strength. Analyses were adjusted for confounders (with and without depressive disorder) and baseline frailty severity. Interactions between personality traits and depressive disorder were examined. RESULTS: All personality traits were associated with change in at least one frailty marker over time. Over time, a higher level of neuroticism was associated with an accelerated increase of frailty, whereas a higher level of extraversion, agreeableness, conscientiousness and openness were associated with an attenuated increase of frailty. None of the associations were moderated by depression. Additional adjustment for depression decreased the strength of the association of neuroticism, extraversion and conscientiousness with frailty. CONCLUSIONS: Personality traits have impact on frailty trajectories in later life. CLINICAL IMPLICATIONS: Underlying pathways and potential modification by psychotherapy merit further study.

Psychotropic drug treatment for agitated behaviour in dementia: what if the guideline prescribing recommendations are not sufficient? A qualitative study.

BACKGROUND: Agitation is a common challenging behaviour in dementia with a negative influence on patient's quality of life and a high caregiver burden. Treatment is often difficult. Current guidelines recommend restrictive use of psychotropic drug treatment, but guideline recommendations do not always suffice. OBJECTIVE: To explore how physicians decide on psychotropic drug treatment for agitated behaviour in dementia when the guideline prescribing recommendations are not sufficient. METHODS: We conducted five online focus groups with a total of 22 elderly care physicians, five geriatricians and four old-age psychiatrists, in The Netherlands. The focus groups were thematically analysed. RESULTS: We identified five main themes. Transcending these themes, in each of the focus groups physicians stated that there is 'not one size that fits all'. The five themes reflect physicians' considerations when deciding on psychotropic drug treatment outside the guideline prescribing recommendations for agitated behaviour in dementia: (1) 'reanalysis of problem and cause', (2) 'hypothesis of underlying cause and treatment goal', (3) 'considerations regarding drug choice', (4) 'trial and error' and (5) 'last resort: sedation'. CONCLUSION: When guideline prescribing recommendations do not suffice, physicians start with reanalysing potential underlying causes. They try to substantiate and justify medication choices as best as they can with a hypothesis of underlying causes or treatment goal, using other guidelines, and applying personalised psychotropic drug treatment.

Candidate CSPG4 mutations and induced pluripotent stem cell modeling implicate oligodendrocyte progenitor cell dysfunction in familial schizophrenia.

Schizophrenia is highly heritable, yet its underlying pathophysiology remains largely unknown. Among the most well-replicated findings in neurobiological studies of schizophrenia are deficits in myelination and white matter integrity; however, direct etiological genetic and cellular evidence has thus far been lacking. Here, we implement a family-based approach for genetic discovery in schizophrenia combined with functional analysis using induced pluripotent stem cells (iPSCs). We observed familial segregation of two rare missense mutations in Chondroitin Sulfate Proteoglycan 4 (CSPG4) (c.391G > A [p.A131T], MAF 7.79 × 10-5 and c.2702T > G [p.V901G], MAF 2.51 × 10-3). The CSPG4A131T mutation was absent from the Swedish Schizophrenia Exome Sequencing Study (2536 cases, 2543 controls), while the CSPG4V901G mutation was nominally enriched in cases (11 cases vs. 3 controls, P = 0.026, OR 3.77, 95% CI 1.05-13.52). CSPG4/NG2 is a hallmark protein of oligodendrocyte progenitor cells (OPCs). iPSC-derived OPCs from CSPG4A131T mutation carriers exhibited abnormal post-translational processing (P = 0.029), subcellular localization of mutant NG2 (P = 0.007), as well as aberrant cellular morphology (P = 3.0 × 10-8), viability (P = 8.9 × 10-7), and myelination potential (P = 0.038). Moreover, transfection of healthy non-carrier sibling OPCs confirmed a pathogenic effect on cell survival of both the CSPG4A131T (P = 0.006) and CSPG4V901G (P = 3.4 × 10-4) mutations. Finally, in vivo diffusion tensor imaging of CSPG4A131T mutation carriers demonstrated a reduction of brain white matter integrity compared to unaffected sibling and matched general population controls (P = 2.2 × 10-5). Together, our findings provide a convergence of genetic and functional evidence to implicate OPC dysfunction as a candidate pathophysiological mechanism of familial schizophrenia.

Predicting rehospitalisation in older inpatients with a psychotic disorder.

OBJECTIVE: The objective of this study was to predict rehospitalisation in a psychiatric clinic in older inpatients with a psychotic disorder. METHODS/DESIGN: In this prospective, observational study, all eligible inpatients aged 55 years and over with a primary psychotic disorder, admitted to a specialised ward for older psychotic patients in a large psychiatric inpatient clinic in the Netherlands, were asked to participate. Whether or not patients were rehospitalised and time to rehospitalisation were assessed 1 year after discharge from the ward. We recorded age, gender, living arrangement, psychiatric diagnosis, severity of psychotic symptoms, duration of index episode, age of onset of psychotic disorder, number of previous admissions, involuntary admission and use of depot medication at discharge. All patients underwent a neuropsychological assessment. RESULTS: Of the 90 patients that were included, 32 (35.6%) had been readmitted within 1 year after discharge. None of the demographic or clinical variables predicted rehospitalisation or the time to rehospitalisation. CONCLUSION: Factors that predict rehospitalisationin younger adult patients with schizophrenia may not predict rehospitalisationin older patients with a psychotic disorder, of which the majority suffered from schizophrenia. We expect that other factors than those investigated may be of greater importance to predict rehospitalisation, as for example social support and coping mechanisms.

Effects of Pharmacogenetic Screening for CYP2D6 Among Elderly Starting Therapy With Nortriptyline or Venlafaxine: A Pragmatic Randomized Controlled Trial (CYSCE Trial).

PURPOSE/BACKGROUND: The duration of untreated depression is a predictor for poor future prognosis, making rapid dose finding essential. Genetic variation of the CYP2D6 isoenzyme can influence the optimal dosage needed for individual patients. The aim of this study was to determine the effectiveness of CYP2D6 pharmacogenetic screening to accelerate drug dosing in older patients with depression initiating nortriptyline or venlafaxine. METHODS/PROCEDURES: In this randomized controlled trial, patients were randomly allocated to one of the study arms. In the intervention arm (DG-I), the specific genotype accompanied by a standardized dosing recommendation based on the patients' genotype and the prescribed drug was directly communicated to the physician of the participant. In both the deviating genotype control arm (DG-C) and the nonrandomized control arm, the physician of the participants was not informed about the genotype and the associated dosing advise. The primary outcome was the time needed to reach adequate drug levels: (1) blood levels within the therapeutic range and (2) no dose adjustments within the previous 3 weeks. FINDINGS/RESULTS: No significant difference was observed in mean time to reach adequate dose or time to adequate dose between DG-I and DG-C. Compared with the nonrandomized control arm group, adequate drug levels were reached significantly faster in the DG-I group (log-rank test; P = 0.004), and there was a similar nonsignificant trend for the DG-C group (log-rank test; P = 0.087). IMPLICATIONS/CONCLUSIONS: The results of this study do not support pharmacogenetic CYP2D6 screening to accelerate dose adjustment for nortriptyline and venlafaxine in older patients with depression.

Electroconvulsive Therapy for Agitation and Aggression in Dementia: A Systematic Review.

OBJECTIVES: Many patients with dementia develop agitation or aggression in the course of their disease. In some severe cases, behavioral, environmental, and pharmacological interventions are not sufficient to alleviate these potentially life-threatening symptoms. It has been suggested that in those cases, electroconvulsive therapy (ECT) could be an option. This review summarizes the scientific literature on ECT for agitation and aggression in dementia. METHODS: We performed a systematic review in accordance with PRISMA guidelines. A search was conducted in Ovid MEDLINE, EMBASE, and PsycINFO. Two reviewers extracted the following data from the retrieved articles: number of patients and their age, gender, diagnoses, types of problem behavior, treatments tried before ECT, specifications of the ECT treatment, use of rating scales, treatment results, follow-up data, and adverse effects. RESULTS: The initial search yielded 264 articles, 17 of which fulfilled the inclusion criteria. Of these studies, one was a prospective cohort study, one was a case-control study, and the others were retrospective chart reviews, case series, or case reports. Clinically significant improvement was observed in the majority (88%) of the 122 patients described, often early in the treatment course. Adverse effects were most commonly mild, transient, or not reported. CONCLUSIONS: The reviewed articles suggest that ECT could be an effective treatment for severe and treatment-refractory agitation and aggression in dementia, with few adverse consequences. Nevertheless, because of the substantial risk of selection bias, the designs of the studies reviewed, and their small number, further prospective studies are needed to substantiate these preliminary positive results.

A Six-Year Prospective Study of the Prognosis and Predictors in Patients With Late-Life Depression.

OBJECTIVES: To examine the six-year prognosis of patients with late-life depression and to identify prognostic factors of an unfavorable course. DESIGN AND SETTING: The Netherlands Study of Depression in Older Persons (NESDO) is a multisite naturalistic prospective cohort study with six-year follow-up. PARTICIPANTS: Three hundred seventy-eight clinically depressed patients (according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision criteria) and 132 nondepressed comparisons were included at baseline between 2007 and 2010. MEASUREMENTS: Depression was measured by the Inventory of Depressive Symptomatology at 6-month intervals and a diagnostic interview at 2- and 6-year follow-up. Multinomial regression and mixed model analyses were both used to identify depression-related clinical, health, and psychosocial prognostic factors of an unfavorable course. RESULTS: Among depressed patients at baseline, 46.8% were lost to follow-up; 15.9% had an unfavorable course, i.e., chronic or recurrent; 24.6% had partial remission; and 12.7% had full remission at six-year follow-up. The relative risk of mortality in depressed patients was 2.5 (95% confidence interval 1.26-4.81) versus nondepressed comparisons. An unfavorable course of depression was associated with a younger age at depression onset; higher symptom severity of depression, pain, and neuroticism; and loneliness at baseline. Additionally, partial remission was associated with chronic diseases and loneliness at baseline when compared with full remission. CONCLUSIONS: The long-term prognosis of late-life depression is poor with regard to mortality and course of depression. Chronic diseases, loneliness, and pain may be used as putative targets for optimizing prevention and treatment strategies for relapse and chronicity.

Lifestyle factors and the course of depression in older adults: A NESDO study.

OBJECTIVES: To investigate whether lifestyle indicators including physical exercise, sleep duration, alcohol use, body mass index, smoking status, and a composite lifestyle index are associated with the depression course in older adults. METHODS: Data of 283 older adults were used from the Netherlands Study of Depression in Older Persons. Depressive disorders at baseline were assessed with the Composite International Diagnostic Interview. The depression course at 2-year follow-up was assessed with the Inventory of Depressive Symptoms (IDS, score 0-84) every 6 months; physical exercise with the International Physical Activity Questionnaire; alcohol use with the Alcohol Use Disorders Identification Test; body mass index by anthropometry; and sleep duration and smoking status by interview questions. A composite lifestyle index was calculated by summing scores assigned to each lifestyle factor, with a higher score indicating healthier behavior. RESULTS: Of all participants, 61.1% had chronic depression (all IDS scores 14-84), 20.1% had intermittent depression (1 IDS score ≤ 14), and 18.7% remitted depression (last 2 IDS scores ≤14). None of the investigated lifestyle indicators, nor the composite lifestyle index was associated with depression course, after adjustment for covariates. CONCLUSIONS: Lifestyle factors do not predict the course of depression at 2-year follow-up in older adults.

Vascular risk factors in older patients with depression: outcome of electroconvulsive therapy versus medication.

OBJECTIVE: Research suggests that in depression, vascular burden predicts a lower efficacy for medication (MED) and a more favourable outcome for electroconvulsive therapy (ECT). Therefore, we investigated the influence of the following vascular risk factors (VRF): hypercholesterolemia, hypertension, smoking, diabetes mellitus, cardiovascular disease, and cerebral vascular accident/transient ischemic attack, on remission from major depression after ECT versus MED. METHODS: The study sample consisted of 81 inpatients with a DSM-IV unipolar major depression diagnosis (mean age 72.2 years, SD = 7.6, mean Montgomery-Åsberg Depression Rating Scale score 32.9, SD = 6.2) participating in a randomized controlled trial comparing nortriptyline versus venlafaxine and 43 inpatients (mean age 73.7 years, SD = 7.5, mean Montgomery-Åsberg Depression Rating Scale score 30.6, SD = 7.1) from an randomized controlled trial comparing brief pulse versus ultrabrief pulse ECT. The presence of VRF was established from the medical records. The remission rate of patients with VRF was compared with those of patients without VRF. RESULTS: The remission rate was 58% (19/33) in the ECT group with ≥1 VRF and 32% (23/73) in the MED group with ≥1 VRF (χ2  = 6.456, p = 0.011). Comparing patients with no VRF versus ≥1 VRF, the remission rate decreased from 80 to 58% (χ2  = 1.652, p = 0.276) in ECT patients and from 38 to 32% (χ2  = 0.119, p = 0.707) in MED patients. Applying different cut-offs for the number of VRFs yielded the same trends. Logistic regression revealed no interaction between VRF and treatment condition. CONCLUSION: The superior efficacy of ECT over pharmacotherapy in major depression in older age was independent of the presence of VRF. Copyright © 2017 John Wiley & Sons, Ltd.

Effect of chronic somatic diseases on the course of late-life depression.

OBJECTIVE: To examine the influence of specific chronic somatic diseases and overall somatic diseases burden on the course of depression in older persons. METHODS: This was a prospective cohort study with a 2-year follow-up. Participants were depressed persons (n = 285) from the Netherlands Study of Depression in Older Persons. The presence of chronic somatic diseases was based on self-report. Diagnosis of depression was assessed with the Composite International Diagnostic Interview, and severity of depression was measured with the Inventory of Depressive Symptomatology Self-report. RESULTS: Cardiovascular diseases (odds ratio [OR] = 1.67, 95% confidence interval [CI] = 1.02-2.72, p = 0.041), musculoskeletal diseases (OR = 1.71, 95% CI = 1.04-2.80, p = 0.034), and the number of chronic somatic diseases (OR = 1.37, 95% CI = 1.16-1.63, p < 0.001) were associated with having a depressive disorder at 2-year follow-up. Furthermore, chronic non-specific lung diseases, cardiovascular diseases, musculoskeletal diseases, cancer, or cumulative somatic disease burden were associated with a chronic course of depression. CONCLUSIONS: Somatic disease burden is associated with a poor course of late-life depression. The course of late-life depression is particularly unfavorable in the presence of chronic non-specific lung diseases, cardiovascular diseases, musculoskeletal diseases, and cancer.

Gender Differences in Cognitive Functioning in Older Alcohol-Dependent Patients.

BACKGROUND: Alcohol dependence is associated with impairments in cognition, especially in later life. Previous studies suggest that excessive drinking has more negative impact on cognition in women than in men. OBJECTIVES: In this study, differences in cognition between male and female older, alcohol-dependent patients were examined. METHOD: Older alcohol-dependent inpatients (N = 164, 62.2% men, mean age 62.6 ± 6.4) underwent neuropsychological tests of sensitivity to interference, mental flexibility, and visual processing. RESULTS: No gender differences were found in age, educational level, estimated premorbid verbal intelligence, and sensitivity to interference. Duration of alcohol dependence was longer for men than for women. Men performed better than women on visual processing, and women better than men on mental flexibility. The superior mental flexibility of women remained significant after adjustment for duration of alcohol dependence. Conclusions/Importance: Older alcohol-dependent inpatients performed below average on cognitive tasks, which suggests that long-term excessive alcohol use negatively affects cognition. Our study does not demonstrate more severe cognitive impairment in women than in men.

Management of Depression in Older Adults: A Review.

IMPORTANCE: Depression in older adults is a common psychiatric disorder affecting their health-related quality of life. Major depression occurs in 2% of adults aged 55 years or older, and its prevalence rises with increasing age. In addition, 10% to 15% of older adults have clinically significant depressive symptoms, even in the absence of major depression. OBSERVATIONS: Depression presents with the same symptoms in older adults as it does in younger populations. In contrast to younger patients, older adults with depression more commonly have several concurrent medical disorders and cognitive impairment. Depression occurring in older patients is often undetected or inadequately treated. Antidepressants are the best-studied treatment option, but psychotherapy, exercise therapy, and electroconvulsive therapy may also be effective. Psychotherapy is recommended for patients with mild to moderate severity depression. Many older patients need the same doses of antidepressant medication that are used for younger adult patients. Although antidepressants may effectively treat depression in older adults, they tend to pose greater risk for adverse events because of multiple medical comorbidities and drug-drug interactions in case of polypharmacy. High-quality evidence does not support the use of pharmacologic treatment of depression in patients with dementia. Polypharmacy in older patients can be minimized by using the Screening Tool of Older Persons Prescriptions and Screening Tool to Alert doctors to Right Treatment (STOPP/START) criteria, a valid and reliable screening tool that enables physicians to avoid potentially inappropriate medications, undertreatment, or errors of omissions in older people. Antidepressants can be gradually tapered over a period of several weeks, but discontinuation of antidepressants may be associated with relapse or recurrence of depression, so the patient should be closely observed. CONCLUSIONS AND RELEVANCE: Major depression in older adults is common and can be effectively treated with antidepressants and electroconvulsive therapy. Psychological therapies and exercise may also be effective for mild-moderate depression, for patients who prefer nonpharmacological treatment, or for patients who are too frail for drug treatments.

Detecting delirium in elderly outpatients with cognitive impairment.

BACKGROUND: Delirium may be more prevalent in elderly outpatients than has long been assumed. However, it may be easily missed due to overlap with dementia. Our aim was to study delirium symptoms and underlying somatic disorders in psycho-geriatric outpatients. METHODS: We performed a case-control study among outpatients that were referred to a psychiatric institution between January 1st and July 1st 2010 for cognitive evaluation. We compared 44 cases with DSM-IV delirium (24 with and 20 without dementia) to 44 controls with dementia only. All participants were aged 70 years or older. We extracted from the medical files (1) referral characteristics including demographics, medical history, medication use, and referral reasons, (2) delirium symptoms, scored with the Delirium Rating Scale-Revised-98, and (3) underlying disorders categorized as: drugs/intoxication, infection, metabolic/endocrine disturbances, cardiovascular disorders, central nervous system disorders, and other health problems. RESULTS: At referral, delirium patients had significantly higher numbers of chronic diseases and medications, and more often a history of delirium and a recent hospital admission than controls. Most study participants, including those with delirium, were referred for evaluation of (suspected) dementia. The symptoms that occurred more frequently in cases were: sleep disturbances, perceptual abnormalities, delusions, affect lability, agitation, attention deficits, acute onset, and fluctuations. Drug related (68%), infectious (61%), and metabolic-endocrine (50%) disturbances were often involved. CONCLUSIONS: Detection of delirium and distinction from dementia in older outpatients was feasible but required detailed caregiver information about the presence, onset, and course of symptoms. Most underlying disorders could be managed at home.

Early Complete Remitters After Electroconvulsive Therapy: Profile and Prognosis.

OBJECTIVE: To investigate the prevalence, characteristics, and prognosis of depressive patients who show early complete remission after right unilateral (ultra)brief pulse electroconvulsive therapy (ECT). METHODS: Early complete remitters (ECRs) were those patients who were rated 1 on the Clinical Global Impression Scale (maximum score, 7) within 4 ECT sessions and achieved remission (Montgomery Åsberg Depression Rating Scale score, <10). The ECRs were compared with late complete remitters (LCRs), which fulfilled the same criteria after 9 to 12 ECT sessions and with the nonremitters/nonresponders (NRs). RESULTS: Of the 87 patients who completed the index treatment phase, 50 (57.5%) achieved remission. Of these remitters, 12 (14%) were ECRs and 9 (10%) were LCRs. The ECRs were characterized by a higher mean age (71.0 vs 53.9 years; P = 0.008), a shorter current depressive episode (mean, 5.8 vs 15.4 months; P = 0.042), and more psychotic features (75% vs 22%; P = 0.030) and were treated more often with brief pulse ECT (P = 0.030) compared with the LCRs. Although not significant, cognitive performances of ECRs were lower than that of LCRs at baseline with a large effect size: Autobiographical Memory Interview (P = 0.099; d = 0.83), Amsterdam Media Questionnaire (P = 0.114; d = 0.84), and Letter fluency (P = 0.071; d = 0.95). The ECR group had a lower relapse rate during 6 months' follow-up: 10% (1 of 10) versus 62.5% (5 of 8) (P = 0.043). No significant differences in demographic and clinical characteristics were found between LCRs (n = 9) and NRs (n = 27). CONCLUSIONS: Older patients with a psychotic depression and a profile of cognitive slowing have a high chance of achieving complete remission within 4 ECT sessions, with a favorable 6-month prognosis.

Speed of remission in elderly patients with depression: electroconvulsive therapy v. medication.

BACKGROUND: Severe depression can be a life-threatening disorder, especially in elderly patients. A fast-acting treatment is crucial for this group. Electroconvulsive therapy (ECT) may work faster than medication. AIMS: To compare the speed of remission using ECT v. medication in elderly in-patients. METHOD: The speed of remission in in-patients with a DSM-IV diagnosis of major depression (baseline MADRS score ≥20) was compared between 47 participants (mean age 74.0 years, s.d. = 7.4) from an ECT randomised controlled trial (RCT) and 81 participants (mean age 72.2 years, s.d. = 7.6) from a medication RCT (nortriptyline v. venlafaxine). RESULTS: Mean time to remission was 3.1 weeks (s.d. = 1.1) for the ECT group and 4.0 weeks (s.d. = 1.0) for the medication group; the adjusted hazard ratio for remission within 5 weeks (ECT v. medication) was 3.4 (95% CI 1.9-6.2). CONCLUSIONS: Considering the substantially higher speed of remission, ECT deserves a more prominent position in the treatment of elderly patients with severe depression.

Two years' outcome of acute mania in bipolar disorder: different effects of age and age of onset.

BACKGROUND: Information about differences between younger and older patients with bipolar disorder and between older patients with early and late age of onset of illness during long-term treatment is scarce. OBJECTIVES: This study aimed to investigate the differences in treatment and treatment outcome between older and younger manic bipolar patients and between early-onset bipolar (EOB) and late-onset bipolar (LOB) older patients. METHOD: The European Mania in Bipolar Longitudinal Evaluation of Medication study was a 2-year prospective, observational study in 3459 bipolar patients on the treatment and outcome of patients with an acute manic or mixed episode. Patients were assessed at 6, 12, 18, and 24 months post-baseline. We calculated the number of patients with a remission, recovery, relapse, and recurrence and the mean time to achieve this. RESULTS: Older patients did not differ from younger bipolar patients in achieving remission and recovery or suffering a relapse and in the time to achieve this. However, more older patients recurred and in shorter time. Older patients used less atypical antipsychotics and more antidepressants and other concomitant psychiatric medication. Older EOB and LOB patients did not differ in treatment, but more older LOB patients tended to recover than older EOB patients. CONCLUSION: Older bipolar manic patients did not differ from younger bipolar patients in short-term treatment outcome (remission and recovery), but in the long term, this may be more difficult to maintain. Distinguishing age groups in bipolar study populations may be useful when considering treatment and treatment outcome and warrants further study.

Social factors and readmission after inpatient detoxification in older alcohol-dependent patients.

BACKGROUND AND OBJECTIVES: Alcohol dependence is often a chronic relapsing disorder with frequent admissions to inpatient facilities. This study in older alcohol-dependent inpatients investigates the role of social factors in readmissions after inpatient detoxification. METHODS: In a prospective study, 132 older alcohol-dependent patients admitted to inpatient detoxification (mean age 63.4, SD = 6.6, 39.4% women) were interviewed with the European version of the Addiction Severity Index (Europ-ASI). Readmission to inpatient treatment was monitored up to 1 year after discharge. The effect of social factors on readmission, the number of readmissions and the time to first readmission was established using group comparisons, Poisson regression analysis, and Cox' proportional hazards regression analysis, respectively. RESULTS: Sixty-seven (50.8%) of the 132 patients were readmitted within 1 year. In this group, the median number of readmissions was 2 (IQR = 2, range 1-6) and the median time to first readmission was 88 days (IQR = 116, range 3-356). In a multivariate analysis, spending most leisure time alone predicted fewer readmissions. None of the other social factors predicted readmission, number of readmissions or time to first readmission. DISCUSSION AND CONCLUSIONS: Rehospitalization of older alcohol-dependent patients after detoxification is very common, and generally not predicted by social factors. Only spending most leisure time alone may play a role. SCIENTIFIC SIGNIFICANCE: This study shows that most social factors are-unexpectedly-not associated with rehospitalization of older alcohol-dependent patients after detoxification. "Spending leisure time alone" warrants further study as a potentially modifiable predictor.

Decrease in unmet needs contributes to improved motivation for treatment in elderly patients with severe mental illness.

PURPOSE: To investigate the pattern of associations between changes in unmet needs and treatment motivation in elderly patients with severe mental illness. METHODS: Observational longitudinal study in 70 patients treated by an assertive community treatment team for the elderly. Unmet needs and motivation for treatment were measured using the Camberwell assessment of needs for the elderly and the stages-of-change (SoC) scale, respectively, at baseline, after 9 and 18 months. SoC scores were dichotomized into two categories: motivated and unmotivated. Multinomial logistic regression analyses were conducted to determine whether changes in motivation were parallel to or preceded changes in unmet needs. RESULTS: The number of patients who were not motivated for treatment decreased over time (at baseline 71.4 % was not motivated, at the second measurement 51.4 %, and at 18 months 31.4 % of the patients were not motivated for treatment). A decrease in unmet needs, both from 0-9 to 0-18 months was associated with remaining motivated or a change from unmotivated to becoming motivated during the same observational period (parallel associations). A decrease in unmet needs from 0 to 9 months was also associated with remaining motivated or a change from unmotivated to motivated during the 9-18 months follow-up (sequential associations). CONCLUSIONS: Our findings suggest that a decrease in unmet needs is associated with improvements in motivation for treatment.

Correlates of alcohol abstinence and at-risk alcohol consumption in older adults with depression: the NESDO study.

OBJECTIVES: To compare alcohol use between depressed and nondepressed older adults, and to investigate correlates of alcohol abstinence and at-risk alcohol consumption in depressed older adults. DESIGN: Cross-sectional study. SETTING: Netherlands Study of Depression in Older Persons (NESDO). PARTICIPANTS: A total of 373 participants (mean [standard deviation] age: 70.6 [7.3] years; 66% women) diagnosed with a depressive disorder, and 128 nondepressed participants. MEASUREMENTS: Alcohol use was assessed with the Alcohol Use Disorders Identification Test (AUDIT). Participants were categorized into abstainers (AUDIT score: 0), moderate drinkers (AUDIT score: 1-4), and at-risk drinkers (AUDIT score: ≥5). Multinomial logistic regression analysis was performed with AUDIT categories as outcome, and demographic, social, somatic, and psychological variables as determinants. RESULTS: The depressed group consisted of 40.2% abstainers, 40.8% moderate drinkers, and 19.0% at-risk drinkers. The depressed participants were more often abstinent and less often moderate drinkers than the nondepressed participants; they did not differ in at-risk drinking. Depressed abstainers more often used benzodiazepines but less often used antidepressants, and they had a poorer cognitive function than depressed moderate drinkers. Depressed at-risk drinkers were more often smokers and had fewer functional limitations but more severe depressive symptoms than depressed moderate drinkers. CONCLUSIONS: Although alcohol abstinence was more common in depressed than in nondepressed older adults, 19% of depressed persons were at-risk drinkers. Because at-risk drinking is associated with more severe depression and may have a negative impact on health and treatment outcome, it is important that physicians consider alcohol use in depressed older adults.
